[news.eclipse.modeling.mdt.uml2] Re: Coupling operations with activities

[Nick Betteridge <nick.betteridge@xxxxxxxxxxxxxx>]

Hi Rafael

Thanks for replying. The section of the spec (Concrete Syntax for a UML 
Action Language) was the appendix - a simple  java method and the 
corresponding activity diagram. I can see how to generate the class and 
the operation, and also generate the activity with CallBehaviourActions. 
So, from what you are saying, all I have to do is create the activity 
and do a getMethods().add()?

ie:

class ListUtils {
    boolean sameSizeLists(List listOne, List listTwo) {
        if (listOne.size() == listTwo.size())
            return true;
        return false;
    }
}

Class class = package_.createOwnedClass("ListUtils", isAbstract);

Operation op = class.createOwnedOperation("sameSizeLists", pNames, 
pTypes, returnType);

Activity activity = (Activity) 
class.createOwnedBehavior("sameSizeLists", 
UMLPackage.eINSTANCE.getActivity());

CallBehaviorAction cba0 = (CallBehaviorAction) 
activity.createNode(null,UMLPackage.eINSTANCE.getCallBehaviorAction());

... add actions, nodes etc

op.getMethods().add(activity);


.... and then when it comes to traversing the model (for code 
generation), look at the methods  assigned to the operation and choose 
the most appropriate?


Thanks again

Cheers

Nick
